Primer question

I scraped the acoustic off the ceiling and sanded it down, then sprayed splatter texture and drug it down. Since the ceilng was white already do you recommend still going back with a sealer even though it it going back white?

Now on the walls with the new sheetrock on it. I did same finish on it. What kind of sealer would you recommend, walls are going back a light beigh. Should Iuse kill seal or what on them. It is a large walk in closet. A 10 x 10 bedroom converted to a walk in closet.

I hope you 'skim-coated' the cieling after you removed the popcorn, or the seams will show through. Yes, even IF you sanded and did a knockdown texture afterwards.

ALWAYS prime-n-seal before painting! I too would ues the 1-2-3 by Zinzzer good stuff!

You might want to check with a drywall supplier for a 'Hamilton's' primer/pre-prime product that's supposed to 'even-up' the finish on knockdown textures better than just the primer. What typically happens [even when primed] is that the low spots will shine, or flash through and the finish will look uneven ... especially in side light. Flat finish will minimize this, but it is still noticeable to the trained eye. Most people wouldn't know a good job from bad if it jumped up and bit them in the nose or on their ___! I'd say at a MINIMUM ... Prime with Zinzzer 1-2-3 ! And don't be afraid to lay it on ... 2 coat everything ... unless you're trying to get away cheap then go get some mistints and P___-Coat it
